    Viscometric Study on the Interaction Between Hydrophobically Modified Poly(acrylic acid) and Np7.5

      摘要
    • 摘要: 研究了氟基团改性和氟碳、碳氢基团同时改性的聚丙烯酸（HM－PAA）以及参与聚合物（PAA）与非离子表面活性剂Np7.5分别在稀溶液和亚浓溶液下的相互作用对特性粘数和Brookfield表观粘度的影响。结果表明，PAA与Np7.5无明显作用，而M－PAA在Np7.5达到一定浓度后，由于Np7.5参与了疏水缔合，特性粘数和表观粘度发生了明显变化。稀溶液中，氟碳基团较多的聚合物出现了链构象的伸展。亚浓溶液中，疏水改性聚合物的粘度都有先上升后下降的变化，但氟碳含量较多的变化更强烈。
